Question on: JAMB Physics - 2022
Which expression gives the magnetic flux?
A
qVB sin\(\theta\)
B
\(\frac{\mu \phi I}{2 \pi r}\)
C
BA cos \(\theta\)
D
-N \(\frac{d \phi}{dt}\)

Correct Option: C
Magnetic flux is a measurement of the total magnetic field which passes through a given area.Â
Mathematically, it is the surface integral of the normal component of the magnetic field (B) passing through that surface.
Magnetic force is often denoted Φ or ΦB, with the SI unit Weber
B = Φ/A
Where:
B is magnetic flux density in teslas (T)
Φ is magnetic flux in webers (Wb)
A is area in square meters (m2).
